GENERA OF THE NITROGEN FIXING TREES
From: James Brewbaker
[based on Brewbaker et al. 1990 - see References]
A summary table is provided of trees and large shrubs (> 3 m
high) that were validated as nodulating, and known or presumed
to fix nitrogen. The summary is derived from NFTA's expanded
database that includes about 1500 taxa. Only one family that
includes nodulating plants, the Datiscaceae, does not appear in
this table, as the genus Datisca lacks arboreal or woody forms.
Most of the 115 genera of N-fixing trees and shrubs (NFT) are
legumes. As calculated by de Faria et. al. (1989) nodulation
characterized 23% of 349 tested caesalpinioid species, 90% of
454 tested mimosoids and 97% of the 2592 papilionids.
Nodulation involves symbiosis with rhizobial bacteria in the
legume and in the genus Parasponia (and possibly other taxa in
the Ulmaceae). All other non-leguminous genera are nodulated by
actinomycetes of the genus Frankia.

CONFERENCE: PEATLANDS FOR PEOPLE IN VANCOUVER B.C.
Where: George Curtis Law Building, University of British Colum-
bia, Vancouver, B.C.
When: January 26-28, 1996
The conference "Peatlands for people" is organized by the Burns
Bog Conservation Society. Its goal is "to explore and advance
multi-stakeholder actions for achieving sustainability of
world's disappearing peatlands."
The speakers will include Jim Pojar (rare aquatic and wetland
plants), Allen Banner (peatlands in British Columbia), Richard
Hebda (discussion on Burns Bog), Martin Gabauer (Sandhill Cranes
in Burns Bog), Anne Brown (methane production in peatlands),
Ralph May (use of peatlands for cranberry farming), Tony Cable
(peatlands and peat extraction), Alison Gail (eco-sites and
tourism within metropolitan communities). The well known English
botanist, writer and TV personality Dr. David Bellamy was in-
vited as a keynote speaker (Celebration of mires/peatlands).

THE EUROPEAN MAGAZINE LOOKS AT CRAWLING THROUGH CYBERSPACE
From: The European MagAZine No. 279 (14-20 Sept. 1995) p.6,7.
The Internet grew up in such an unregulated way that no one
really knows exactly how much is really out there in cyberspace.
As any net user will tell you, trying to find what you want can
be difficult and time-consuming. There is no comprehensive
Internet telephone book that allows you to look up someones's
net address (URL).
So what can the baffled netsurfer do? If you want to find a web
page related to your favourite group etc., you crawl. Crawling
the web in search of URLs Usenet or newsgroups is a serious
business. A search engine is the name given to the programs and
Internet resources dedicated to crawling. Some are commercial,
others are free.
http://fuzine.mt.cs.cmu.edu/
Lycos - the king of the online search engines. This massive
database, maintained by Carnegie Mellon University, is the
first place you should go to on your web search.
http://akebono.stanford.edu/yahoo
Yahoo web crawler has the only disadvantage that it is biased
towards US sites. European web sites often fail to get recog-
nized or fail to post their URL.
http://harvest.cs.coloradu.edu/
Harvest contains more than 25,000 3w sites with fewer
duplications than Lycos.

http://info.cern.ch/hypertext/Data Sources/bySubject/Overview.html
These are one of the most essential and powerful search tools
on the net.
http://cui_www.unige.ch/w3catalog
CUI index is mainatined by the Centre Universitaire
d'Informatique in Geneva. It is a well maintained database
which allows you to search existing web catalogues and
produce detailed summaries and links. It has around 13,000
entries so you should have no trouble getting what you need.
PLANTS DATABASE FOR WASHINGTON STATE AND OTHER STATES OF THE USA
From: "John A. DeLapp"
originally posted on
For those folks with Web access the PLANTS database allows the
downloading of a list of Washington state plants from the fol-
lowing URL:
http://trident.ftc.nrcs.usda.gov/plants/staselec.html
The data file can be imported into any spreadsheet, database, or
word processor. (If you are lucky enough to use a Macintosh, you
can use the shareware macro program TypeIt4Me to allow you to
type the abbreviation (symbol) of the name and have the Mac
enter the full name automatically within any program.)
